Avengers #13 (1965)

This book introduced “The Maggia,” so named because the Comics Code would not approve any publication that used the term “Mafia,” and the character Count Nefaria. Nefaria is introduced as a crime lord who wants to take down The Avengers because they’re bad for the crime business. He’s also a robotics expert, and he makes his own fake Avengers team and uses them to trash the team’s rep in the community. One thing he is not is super-powered. That comes later in the character’s history.
